[0002] A cold heading machine is a device that cuts and cold-extrudes processed metal wires, causing the wires to be cold-headed in a mold. It can be used to process various fasteners such as screws. The flip clamp of the cold heading machine is used to clamp the workpiece during the cold heading process. Existing technologies have safety issues during the billet ejection process in cold heading machines. This can cause the billet to fly off the worktable during ejection, potentially resulting in it colliding with other equipment on the worktable and reducing safety. To address this, we propose a safe billet ejection mechanism for cold heading machines. Utility Model Content

During this process, the stepper motor 72 is started. The output end of the stepper motor 72 drives the rotating shaft 73 to rotate, which in turn drives the cam 74 to rotate. The cam 74 drives the horizontal plate 75 to move back and forth. The horizontal plate 75 drives the L-shaped moving plate 76, the displacement plate 77 and the ejector column 78 to move. The L-shaped moving plate 76 slides relative to the guide column 79. The L-shaped moving plate 76 compresses and rebounds the spring 711.
